Complementary and Alternative Medicine for Dysmenorrhea Caused by Endometriosis: A Review of Utilization and Mechanism

Differences in characteristics and use of complementary and alternative methods for coping with endometriosis-associated acyclic pelvic pain across adolescence and adulthood

Introduction

Over four million women in the US alone have been diagnosed with endometriosis. For those living with this disease, surgery and hormonal treatment reduce associated pelvic pain in some, while others continue to experience life impacting pain. Therefore, identification of accessible and cost-effective methods of pain reduction to compliment current treatment is urgently needed. Our objective was to quantify the prevalence of complementary and alternative methods used to manage acyclic pelvic pain and their reported benefit among women of different age groups living with endometriosis.

Methods

We used baseline questionnaire data from laparoscopically-confirmed endometriosis cases who completed a WERF EPHect compliant questionnaire in the longitudinal cohort of The Women's Health Study: From Adolescence to Adulthood (A2A). Participants with acyclic pelvic pain were asked to indicate specific methods or activities that either helped or worsened their pelvic/lower abdominal pain. Differences among age groups [adolescent (<18 years), young adult (18-25 years), and adult (>25 years)] were assessed using Fisher's exact test.

Results

Of the 357 participants included in analysis, sleep for coping was reported more frequently among adolescents (n = 59, 57.3%) compared to young adults (n = 40, 44.0%) and adults (n = 19, 31.1%; p = 0.004). Adolescents also reported more frequent use of music (n = 29, 21.2%) than young adults (n = 10, 7.0%) and adults (n = 7, 9.1%; p = 0.001). Exercise worsened pain most commonly among adolescents (n = 82, 59.9%), followed by younger adults (n = 67, 46.9%), and adults (n = 27, 35.1%; p = 0.002).

Discussion

Our analysis of participants in the A2A cohort showed that the prevalence of complementary and alternative methods used for coping with endometriosis-associated acyclic pelvic pain varied by age group. Future studies should aim to provide information that will further inform decisions in making care plans for managing endometriosis-associated pain that is effective, accessible, and tailored to the preferences of the patient.

Patient prognosis and prediction model for taking Kampo formulas in dysmenorrhea: An observational study

Two representative Kampo formulas, keishibukuryogan and tokishakuyakusan, are frequently prescribed for patients with dysmenorrhea. We previously constructed a model that could predict which of these 2 formulas was most suitable, which is based on 4 subjective symptoms and 3 objective signs. To evaluate the prognosis of patients with dysmenorrhea using the established prediction model and assess the treatment outcomes between those treated in accordance with the prediction model and those who received various other treatments. In this retrospective, observational study, we included patients with menstrual pain who visited the Kampo Clinic at the Keio University Hospital for the first time between October 2014 and December 2020. These patients were monitored over a 90-day follow-up period. Participants were categorized into 2 groups: model-accordance and various-options. The progression of visual analogue scale (VAS) values was evaluated by determining the slopes from regression analysis between these 2 groups, with changes corroborated by the medical records. The study comprised 57 patients: 37 in the model-accordance group and 20 in the various-options group. Notably, the various-options group reported a significantly higher number of subjective symptoms (P = .03). The VAS value showed a decline, as indicated by the negative slope value of the regression line, across both groups - irrespective of their classification. There were no significant differences in the occurrence of adverse events between the 2 groups. The prognosis of patients with dysmenorrhea and the incidence of adverse events remained consistent, regardless of whether the treatment approach was in accordance with the prediction model or varied. Further studies are warranted to assess the prognosis when Kampo formulas are chosen based on the prediction model in the various-options population.

Acupressure application to relieve postpartum uterus pain during breastfeeding: A randomized controlled study

OBJECTIVE

Postpartum uterus pain while breastfeeding is a situation that can affect mother-infant bonding negatively and is a matter of concern for women. The purpose of this study is to investigate the effectiveness of acupressure application in reducing postpartum uterus pain during breastfeeding.

METHODS

This prospective randomized controlled trial was carried out at a maternity hospital in northwestern Turkey between March and August 2022. The sample of the study included 125 multiparous women who were in the 6th to 24th hours after vaginal delivery. The participants were randomly divided into acupressure and control groups. Visual Analog Scale (VAS) was used to evaluate postpartum uterine pain.

RESULTS

While the VAS scores of the acupressure and control groups were similar before breastfeeding, the scores of the acupressure group at the 10th and 20th minutes of breastfeeding were lower (respectively, p = 0.038 and p = 0.011). In the intragroup comparisons, compared to their values before breastfeeding, the pain score of the acupressure group decreased at a statistically highly significant degree at the 20th minute of breastfeeding (p<0.001), whereas the score of the control group increased at a statistically highly significant degree at the 10th and 20th minutes (p<0.001).

CONCLUSION

It was concluded that acupressure can be an effective nonpharmacological method in reducing uterus pain while breastfeeding in the postpartum period.

Ethanol extract of basil (Ocimum Basilicum L.) leaves inhibits endometriosis growth in a mouse model by modulating vascular endothelial growth factor (VEGF) expression

The objective of this study was to examine the effect of administering an ethanol extract obtained from basil leaves on the expression of vascular endothelial growth factor (VEGF) and the severity of endometriosis lesions in a mouse model. A total of 28 female mice, aged 2-3 months and weighing 20-30 grams, were randomly divided into four groups: the control group (C), treatment group 1 (T1) receiving a dose of basil leaf ethanol extract (0.21 mg/g-BW), treatment group 2 (T2) receiving a higher dose (0.42 mg/g BW), and treatment group 3 (T3) receiving the highest dose (0.84 mg/g-BW). Each group underwent a 14-day treatment period, and tissue samples were collected on the 29th day. An immunohistochemical examination was conducted to assess the expression of VEGF and evaluate the severity of endometriosis lesions. The statistical analysis of VEGF expression revealed a significant difference (p=0.026; p<0.05), with the most pronounced effects observed when administering basil leaf ethanol extract at doses of 0.21 mg/g-BW and 0.42 mg/g-BW. Although not statistically significant (p=0.271; p<0.05), a reduction in the severity of endometriosis lesions was observed following the administration of basil leaf ethanol extract at doses of 0.21 mg/g-BW and 0.42 mg/g-BW. Administering basil leaf ethanol extract at doses of 0.21 mg/g-BW and 0.42 mg/g-BW effectively decreased VEGF expression and limited the severity of endometriosis lesions.

Complementary therapy for endometriosis related pelvic pain

In the setting of a global pandemic, it is vastly important now more than ever that patients have agency and control over pain management when living with a debilitating chronic pain disease such as endometriosis. We present a review of the available literature on the most popular and easily accessible complementary pain management therapies for endometriosis including Transcutaneous Electrical Nerve stimulator (TENS) units, diets, Cannabidiol (CBD), turmeric, meditation, yoga, and acupuncture. These are worthwhile recommendations; however, the data for each is limited and more research is needed to further support each of its use.

Effects of auricular acupressure on dysmenorrhea: A systematic review and meta-analysis of randomized controlled trials

Background

Auricular acupressure (AA) is widely used in treatment of dysmenorrhea, but the safety and efficacy of auricular acupressure on dysmenorrhoea are still lack of evidence-based basis.

Objective

The purpose of meta-analysis was to evaluate the effects of auricular acupressure on dysmenorrhea.

Data sources

A systematic search was conducted in six electronic databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials (CINAHL), Weipu (CQVIP), China National Knowledge Infrastructure (CNKI), and Wanfang databases, to retrieve studies published from the inception dates to June 10, 2022.

Study selection

Randomized controlled trials (RCTs) that investigated the effectiveness of AA on dysmenorrhea were identified.

Data extraction and synthesis

The data extraction and quality assessment of the included studies were performed by two reviewers independently. Outcomes were abstracted to determine the effect measure by using mean differences (MD), standardized mean differences (SMD), or odds ratio (OR) from a random effects model.

Main outcomes and measures

Cure rate, total effective rate, and visual analogue scale (VAS) were described as primary outcomes; Short-form Menstrual Distress Questionnaire (MDQs), symptom scores, serum nitric oxide (NO) level, and adverse events were recorded as secondary outcomes.

Results

Thirty-five RCTs involving 3960 participants were included in this study. Our findings indicated that, overall, AA was associated with a significant benefit in cured rate (OR = 1.95, 95%CI: [1.34, 2.83], P=0.0004, I2 = 75%), total effective rate (OR = 3.58, 95%CI: [2.92, 4.39], P<0.00001, I2 = 67%), VAS score (MD = -1.45, 95%CI: [-1.73, -1.17], P<0.00001, I2 = 67%), and symptom scores compared to the control group (SMD = -0.85, 95%CI: [-1.28, -0.43], P<0.0001, I2 = 91%). However, no difference in serum NO (SMD = 0.77, 95%CI: [-0.39, 1.92], P = 0.19, I2 = 89%) and MDQs (SMD = -0.58, 95%CI: [-1.26, 0.10], P = 0.10, I2 = 79%) was found between the two groups. Furthermore, subgroup analysis results indicated that AA showed significant superiorities in increasing cured rate and total effective rate, and reducing VAS score and symptom scores when compared to analgesics and non-intervention. Moreover, AA presented the same superiorities when used as an adjunctive strategy to other therapy. However, these benefits were not detected in AA used alone when compared to the therapies, including Chinese herbs, acupuncture, external application of Chineseherbal medicine, moxibustion, auricular needle, and health education.

Conclusions

Overall, AA, as a potential safety therapy, is effective for the management of dysmenorrhea, such as increasing cured rate, total effective rate, VAS, and symptom scores. Nevertheless, AA showed no significant improvement in serum NO and MDQs. It is furtherly found that AA used alone is superior to analgesics and non-intervention regarding cured rate, total effective rate, VAS, and symptom scores. Furthermore, the same superiorities are observed when AA serves as an adjunctive strategy to other therapy. However, AA alone has little effect on them compared to other therapies, and there is no definite conclusion on the benefits of AA compared to placebo for patients with dysmenorrhea. Rigorous RCTs with blind method and placebo control are warranted to confirm these findings.

Huayu Sanjie Enema Liquid Relieves Pain in Endometriosis Model Rats by Inhibiting Inflammation, Peripheral Sensitization, and Pelvic Adhesion

The objective of this study is to observe the effect of relieving pain of Huayu Sanjie enema liquid (HYSJ-EL) on endometriosis model rats and to explore its mechanism of action. Of 24 female Sprague Dawley rats, six were randomly selected as the sham operation group (normal control group). The remaining rats were used to establish rat models of endometriosis through autologous endometrial transplantation combined with estrogen injection. Successfully modeled rats were randomly divided into the model, indomethacin (Western medicine group), and HYSJ-EL (Chinese herbs group) treatment groups. The thermal pain threshold of rats was measured, and hematoxylin and eosin staining was used to observe pathological changes after sampling. Serum levels of prostaglandin E2 (PGE2), interleukin-6 (IL-6), macrophage inflammatory protein-2 (MIP-2), plasminogen activator inhibitor-1 (PAI-1), and transforming growth factor-β (TGF-β) were measured using an enzyme-linked immunosorbent assay (ELISA). Furthermore, the protein and mRNA expression levels of transient receptor potential vanilloid-1 (TRPV1) and tumor necrosis factor-α (TNF-α) in the endometrium and endometriotic lesions were measured using Western blotting and quantitative real-time PCR assays, respectively. Compared to the model group, the heat pain threshold of rats in the HYSJ-EL group was significantly increased (P < 0.01), and the serum levels of PGE2, IL-6, MIP-2, PAI-1, and TGF-β were significantly decreased (P < 0.01), as well as the expression of TRPV1 and TNF-α protein and mRNA in the tissue of the ectopic lesion was significantly decreased (P < 0.05). These results indicate that the Huayu Sanjie enema liquid exerts analgesic effects on endometriosis by inhibiting inflammation, peripheral nerve sensitization, and pelvic adhesion.

Current Research on Complementary and Alternative Medicine in the Treatment of Premature Ovarian Failure: An Update Review

Complementary and alternative medicine (CAM) encompasses a wide range of different non-mainstream therapies that have been increasingly used for the treatment or adjunct treatment of various ailments, with premature ovarian failure (POF) being one of the most common conditions treated with CAM. This review updates the progress of CAM in the treatment of POF, and we focus specifically on reviewing the evidence for the efficacy and mechanisms of a range of CAM treatments in POF, including single herbal medicines and their active ingredients, compound Chinese medicines, acupuncture and moxibustion, psychotherapy, exercise, vitamins, massage, and dietary supplements. According to the literature, CAM is very helpful for improving POF symptoms, and we hope to provide some instructive suggestions for clinical treatment and experimental research in the future. However, more clinical trials are needed to prove the safety of CAM.

Complementary and Alternative Medicine for Premature Ovarian Insufficiency: A Review of Utilization and Mechanisms

Premature ovarian insufficiency (POI) is defined as a decline in ovarian function before the age of 40 and is one of the leading causes of infertility in women. The etiology is complex, and the pathogenesis is not clear. The main treatment is hormone replacement therapy, but a growing body of data confirms that such treatment can increase the risk of endometrial disease and cardiovascular disease. Complementary and alternative medicine (CAM) has been widely used in patients with POI due to its limited adverse reactions and high efficiency. According to literature reports, CAM therapy for POI mainly includes traditional Chinese medicine, acupuncture, psychotherapy, dietary supplements, and exercise therapy. This article reviews the application of CAM in the treatment of POI and attempts to determine the therapeutic effects and the mechanisms behind these effects based on existing clinical and experimental studies in order to provide theoretical support for the treatment of POI.
